Utility model content

Technical problem to be solved in the utility model is the present situation for prior art, provide a kind of result advantages of simple,The syndeton of wiring board and aluminium base in LED lamp easy to assembly.

The utility model solves the problems of the technologies described above adopted technical scheme: wiring board and aluminium base in a kind of LED lampThe syndeton of plate, comprises wiring board and the aluminium base for mounted LED lamp, it is characterized in that: described circuit edges of boardsEdge stretches out and is formed with a pin, has the conductive foil that corresponds respectively to wiring board both positive and negative polarity on this pin, corresponding,On described aluminium base, have the socket being connected with the inserting of above-mentioned pin phase, and the both sides of this socket be respectively arranged with for phaseAnswer the pad point of conductive foil welding.

As further improvement of the utility model, the both sides of described pin bottom have respectively outward extending card division, instituteState socket and comprise the Part I passing for card division and the Part II matching with pin top, described card division is through socketPart I and move and make the clamping that matches with the Part II of socket of pin top to Part II. Adopt such knotStructure, can prevent that wiring board from moving up and down with respect to aluminium base, is convenient to increase wiring board steady with being connected after aluminium base weldingQualitative.

Further, described conductive foil extends on corresponding card division, and described pad point is located at two of socket Part IISide, under assembling completion status, described card division is pressed on corresponding pad point. Adopt such structure, be convenient to itselfThe conductive foil being just in contact with one another and pad point weld, convenient welding.

As preferably, the edge of described Part II is concaved with the conductive foil that can prevent on pin and aluminium base contacts side surfacesThe mouth of stepping down. If conductive foil contacts with the side of aluminium base, in LED lamp moving process, conductive foil easily and aluminiumThere is friction and cause short circuit in substrate side surfaces, and adopts said structure, effectively avoided the generation of this problem.

Preferably, on described aluminium base, be provided with heat sink, on this heat sink, have the opening passing for pin. LEDLamp directly posts on aluminium base, and the heat of LED lamp can be conducted on heat sink and be dispelled the heat by aluminium base, has strengthenedThe radiating effect of LED lamp.

Compared with prior art, the utility model has the advantage of: the utility model is simple and reasonable, at circuit edges of boardsOn edge, straight forming has pin, and on aluminium base, offers the socket that matches with above-mentioned pin and peg graft, simultaneously at socketBoth sides be provided for pin on the pad point of conductive foil welding, when assembling, directly the pin of wiring board is plugged on slottingIn mouthful, and by the conductive foil on pin and corresponding pad means of spot welds, without by wire or arrange special slottingFitting connects, and has simplified to a great extent the structure of LED lamp, not only easy to assembly, has also saved built-up time,Improve efficiency of assembling.

Detailed description of the invention

Below in conjunction with accompanying drawing, embodiment is described in further detail the utility model.

As shown in Figures 1 to 3, in the LED lamp of the present embodiment, the syndeton of wiring board and aluminium base comprises wiring board 1And for the aluminium base 2 of mounted LED lamp 3, wiring board 1 edge stretches out and is formed with a pin 11, this pin 11On there is the conductive foil 12 that corresponds respectively to wiring board 1 both positive and negative polarity, the conductive foil in the present embodiment is Copper Foil, corresponding,On aluminium base 2, have the socket 21 being connected with above-mentioned pin 11 phase insertings, and the both sides of this socket 21 are respectively arranged with useIn the pad point 22 welding with corresponding conductive foil 12.

Concrete, the both sides of pin 11 bottoms have respectively outward extending card division 111, and socket 21 comprises for card division 111The Part I 211 passing and the Part II 212 matching with pin 11 tops, card division 111 is through socket 21Part I 211 also moves to Part II 212, is matched with the Part II 212 of socket 21 in pin 11 topsClamping, to prevent that wiring board 1 from moving up and down with respect to aluminium base 2, is convenient to increase after wiring board 1 and aluminium base 2 weldingConnective stability. The lower end of two conductive foils 12 extends to respectively on corresponding card division 111, pad point 22 be two alsoBe located at respectively the both sides of socket 21 Part II 212, under assembling completion status, card division 111 is pressed on corresponding padOn point, so that the conductive foil 12 that itself is just in contact with one another welds with pad point 22.

In the present embodiment, the edge of socket 21 Part II 212 is outwards concaved with the conductive foil that can prevent on pin 1112 with aluminium base 2 contacts side surfaces step down mouthfuls 23. If conductive foil 12 contacts with the side of aluminium base 2, at LEDIn lamp moving process, easily there is friction with aluminium base 2 sides and cause short circuit in conductive foil 12, and employing said structure,Effectively avoid the generation of this problem. On aluminium base 2, be provided with heat sink 4, on this heat sink 4, have for pin11 openings that pass 41, LED lamp 3 directly posts on aluminium base 2, and the heat of LED lamp 3 can pass through aluminium base 2Conduct on heat sink 4 and dispel the heat, strengthened the radiating effect of LED lamp.

In the time that the present embodiment is assembled, make the pin 11 of wiring board 1 through the opening 41 on heat sink 4, pinThe card division 111 of 11 bottoms is through the Part I 211 of socket 21, the Part II 212 by wiring board 1 to socket 21Mobile, until pin 11 tops snap in Part II 212 and card division 111 is pressed on the weldering of Part II 212 both sidesMake an inventory on 22, then the conductive foil on card division 111 12 and pad point 22 are welded, compared with prior art,Without by wire or special plug connector is set connects, simplify to a great extent the structure of LED lamp, assemblingConvenient.
